Question about Computers & Internet
Hello Sir / Madam,
Many Acer systems come with the ability to press ALT+F10 to kick off the Acer Recovery applications from a special hidden recovery partition. Sometimes this won’t work and there can be a number of reasons.
1. D2D Recovery is “Disabled” in the BIOS (Main menu).
FIX: Enabled it and try pressing ALT+F10 again as the computer boots.
2. The Acer hidden recovery partition (PQSERVICE) has been removed or damaged. If the disk drive is a replacement drive then you won’t have this partition.
FIX: Unless you have previously imaged the PQSERVICE partition it will not be possible to use D2D recovery. You will need to restore from the Acer Recovery CD/DVD.
3. You have converted the FAT32 partition on the hard drives into NTFS. Acer D2D recovery won’t be available if you perform this conversion. Ironic that NTFS is a more desirable disk format to use but Acer won’t support this in their systems!
FIX: Restore your system from the recovery CD/DVD media.
4. The special Acer Master Boot Record (MBR) has become corrupt or has been overwritten with an non Acer MBR. As long as the PQSERVICE partition is there or you can get your hands on a couple of Acer service files for your model, then you can remake the special Acer MBR. Let’s cover how this is done.
Change the type to “07′ (Installable File System NTFS, HPFS) and “Save Changes”.
mbrwrdos.exe install rtmbr.bin
- You may have to search for these files and change into the relevant directory.
Note: This step writes the Acer MBR, with mbrwrdos.exe and rtmbr.bin being the special service files.
If this is a new drive or someone has completely wiped the drive, including the hidden partitions, it may be necessary to use partitioning software to recreate the partitions that the Acer Recovery system is expecting! You’ll also need to restore an image of the recovery partition from a previously made backup, so it is worth making that backup image straight away while the laptop is still new and shiny, and certainly well in advance of any problem.
A final word or two of caution: take great caution when playing around with partitions on an Acer system… you have been warned… and remember to make the backup media disks as soon as you fire the computer up for the first time!

If you have a system running Vista or Vista x64 and/or Windows 7 or Windows 7 x64, Acer's LOVE to mess up the MBR (Master Boot Record) when you change the OS on the drive or if you install Linux and it goes badly, or you upgrade from Windows XP to Vista... heres how to fix it. Get a copy of HiRens boot cd and boot to it. if your PQSERVICE (Recovery) partition is messed up, follow the instructions above except the drive should be an NTFS filesystem, type: 0x27 (27h). you can use Acronis Disk Director on HiRens to fix this up, and it should be on Disk 1, Partition 1 (the very first partition on the disk), Non-Active status. after the partition is in the correct space and the flags are set correctly, you need to use the utility eXtended FDisk on HiRens, and place a bootloader on the disk...Disk 0, Partition 0 (the first partition, the recovery partition). this will now make your Alt+F10 work... go ahead, reboot your machine to the first Harddrive, it should boot the recovery, the same as though you were to have pressed Alt+F10, only you haven't. now we can get rid of that pesky boot chooser we added, for this we use the utility MBR Tool. Be very careful with this tool, it can cause some real damage if used incorrectly. Choose option 4, you want to play with the MBR, then choose option 9 to write/refresh the bootcode and it will ask you which disk, choose 0, and then choose Source type O for Original. It will follow with a status message elling you it has completed and to press any key. then 'ESC' your way back to the R:\ prompt. Then reboot your system without the HiRens CD and do your Alt+F10 thing and everything should be back exactly as it was from the factory. NOTE: make your active system partition before you intend to recover your machine after correcting the D2D mode, make the partition the size you will need...Usually 75Gig for Vista and 100ish for Win7, that usually suffices with most users, even those that are software heavy, because when you recover to factory it doesn't create or modify partitions, it uses the first it finds beyond the recovery regardless of size or whats in it, and assumes it to be the 'C' drive;)
